Abstract

An opto-mechanical system with a function of focusing light beams is provided. The opto-mechanical system includes a circuit board, a plurality of light-emitting elements mounted on the circuit board, and a light diffusing element placed in front of the light-emitting elements. The light-emitting elements emit point sources. The light diffusing element includes a diffusing surface and a focusing body fixed below the diffusing surface. The diffusing surface diffuses the point sources into a plurality of line sources. The focusing body focuses the plurality of line sources.
